Don't blame the fuel injection necessarily. Check your charging system
at medium RPM's. Should be 13.5V-14.5V at the battery. If it is not,
install a NEW Bosch voltage regulator.
Check the ignition system. Plug wires should be 1000-1500 ohms. Rotor
should measure 2500-5000 ohms. Check the timing.
Check the pressure sensor. Has the adjuster on the end had the epoxy
seal broken. Is it the right one for your system. Is your Engine the
original engine. The car is '68, but the engine/FI could have been
changed, and it now has the cold start injector on it.
